Tap detection on Circuit Playground Bluefruit hypersensitive

[kattni]

Tap detection seems to be more sensitive on Bluefruit than Express. May be worth looking into.

The accelerometer is in the center of the board on CPX, but is to the right of the slide switch on CPB. That could make a difference.

It defaults to all axes, but you can limit to just Z, which should negate the location difference.

In Circuit Python:
`cpx._lis3dh.set_tap(tap=1, threshold=120, time_limit=4, click_cfg=0x10)

Therefore clock_cfg=0x10 Sets to only Z axis, single click.

@kattni Is this resolved?

@dherrada I have not looked into it beyond creating the issue.

Definitely more sensitive on the bluefruit. I know you can set the threshold so my plan is to just raise the tap threshold for the bluefruit so that it behaves like the express does.
